Hi, first off can i just say thank you this is an amazing collection. Being a bit of a noob though have one odd problem. When i load any game the sound is horribly distorted, if i set the output resolution in retro-arch to 1920x1080 60hz, this fixes this issue, however every time i leave a game it resets everything and i have to change it every time. i changed my resolution in Windows to 1920x1080 and this doesn't help, any ideas what i could be doing wrong (if i try to save configuration it says its failed to save, i have tried changing it by just loading retroarch in the C64 Dreams folder and this hasn't saved the setting when loading launchbox) my resolution at present on my monitor is 3840x2160 if that helps. Any advice is much appreciated!
